Men have long been credited with producing the first abstract paintings, yet the true creator was actually a woman—Swedish artist Hilma af Klint, who was inspired by her mystic visions. Returning to early 20th century Stockholm, this fact-based novel by Sofia Lundberg, Alyson Richman, and M.J. Rose tells of Af Klint and the Five, her mysterious group of female painters and writers. Over a century later, the Guggenheim Museum launches a retrospective, and this has life-changing ramifications for curator Eben Elliot.
